RAILROAD-GATE.

Specification of Letters Patent.

Patented Oct. 28, 1919.

Application filed May 7, 1919. Serial No. 295,365.

To all whom it may concern:

Be it known that I, WILLIAM WVIsNIEw- SKI, a citizen of Poland, residingat Flushing, county of Queens, and State of New York, have inventedcertain new and useful Improvements in Railroad-Gates, of which thefollowing is a specification.

This invention relates to improvements in railroad gates and has for itsprincipal object to provide an automatic gate whichis lowered upon theapproach of a train and raised after the passage of said train.

Another object of the invention resides in the provision of anilluminating means which is automatically operated by the lowering andraising of the gate.

With these and other objects in view as will appear as the descriptionproceeds, the invention consists in the novel construction combinationand arrangement of parts as set forth in the following specification,claimed and illustrated in the accompanying drawings, in which,

Figure 1 is a fragmentary side view of a track illustrating the locationof the gates and other details.

Fig. 2 is an enlarged fragmentary view of one of the gates illustratingthe control ling motor.

Fig. 3 is a sectional view through line 33 of Fig. 2.

Fig. 4: is a vertical sectional view through one of the circuitcontrollers.

Fig. 5 is a sectional view through line 5-5 of Fig. 4, and I Fig. 6 is adiagrammatic view illustrating the wiring of the device in detail.

Referring to the drawings in detail the numeral 1 designates a trackrail besidewhich the gates 2 are pivotally mounted between the standards3. The pivot sha'ft a of each gate extends beyond the standard 3 andcarries a large gear wheel 5 which meshes with a pinion 6 on the shaftof the gate controlling motor 7. A pulley 8 is mounted on the motorshaft beside the pinion 6 and around this pulley is a belt 9, the use ofwhich will be more fully hereinafter described.

Mounted beside the track is a housing 10 having a horizontal shaftjournaled therein one end of which carries a pulley 12 around which thebelt 9 runs. A drum 13 of suitable insulating material is secured to theshaft between the walls of the housing and.

attached to the periphery thereof are con tact plates 14 as will beclearly seen upon reference to Figs. 4 and 5. Spring contact fingers 15are attached to the inner faces of the end walls of the housing 10 andtheir free terminals bear upon the periphery of the drum as shown. Thearrangement of these fingers is such that when the drum is partiallyrotated two of said fingers will be in electrical communication.

In the diagram are illustrated the train controlled contacts whichcomprise the housings 16 having secured to their bottom Walls thecontact plate 17 and the spring contacts 18. Plungers 19 are attached tothe spring contacts and extend through the cover of the housings,carrying at their upper ends the treads 20 which are adapted to beengaged by the flanges of the wheels of the train when the sameapproached the crossing.

In operation it will be understood that the power for operating may besupplied by a battery or other power source 21 and when a trainapproaches the crossing from either direction the current will flowthrough the contact springs 18 and contacts 17, thence the springfingers-15 and plates 14 through the motors 7 thereby lowering thegates. Simultaneously with the closing of the circuit the lamps 22 willbe illuminated. After the train has passed, the same engages the treadon the opposite side of the gate and completing the circuit will causethe current to flow through the armatures of the motors in a directionopposite that of the first operation, thus raising the gates andextinguishing the light by breaking the circuit between the lowerfingers 15.

While in the foregoing there has been shown and described the preferredform of this invention it is to be understood that certain minor changesin the construction, combination, and arrangement of parts may beresorted to without departing from the spirit and scope of the inventionas claimed.

What is claimed is,

In a device of the character described the combination of a plurality ofhousings, plungers in said housings extending through the cover thereof,treads at the upper ends of said plungers, adapted to be engaged by theflanges of the wheels of a train of cars, spring contacts within saidhousings at the lower ends of said plunger-s, contact plates connectionWith said plate contacts, and a in said housings, a motor for each gate,a housing, spring contact fingers attached to the slde Walls of saldhouslng 1n electrical the operation of said treads by the flanges of theWheels of a train, for automatically closing said gates by anapproaching train and for opening the same by a departing train.

In testimony whereof I have aflixed my signature.
